Jiayi once published a paper on friction, called "On the Systematic Elaboration and Application of Friction, About the Principle and Use of Bearings", which systematically described friction and the characteristics of friction, and laid a theoretical foundation for the subsequent bearings.

Because of this paper, after Jia Yi became an official mage, he received incomplete feedback from the source sea, and directly blessed the greasy technique, making his greasy technique outstanding.

This can't but be said to be a good thing, although Jia Yi didn't say it, but his heart was also secretly happy for this, and he was a little complacent.

However, when copying the scroll, you need to outline the corresponding spell model in the spiritual sea at the same time, and at the same time steadily output the magic power to the paper, after the two sides are synchronized, the spell model in the spiritual sea resonates with the magic circle on the scroll, and the corresponding spell can be solidified on the paper.

However, the feedback from the source sea made the spell model in the spiritual sea mutate, and when he wanted to draw the scroll of the greasy spell, the spell model in the mutation wanted to bless the magic circle to be formed on the scroll, but the magic circle in the scroll still corresponded to the original old spell model, which was incompatible with the model in the spiritual sea, resulting in the failure of the blessing and the failure of the scroll to portray. This is not an operating system, and the new version will be compatible with the old version.

Jiayi thought about it for a long time before he understood what was going on.

If you want to really draw a greasy scroll, you need to modify the circle in the scroll to make the circle fit the spell model in your mind. Although there is a correspondence between the circle engraved on the scroll and the spell model in my mind, they are not the same thing. Except for some simple spells, the spell model in the spiritual sea is three-dimensional, and the more advanced the spell, the more complex the model, the higher the degree of three-dimensionality, but the magic circle on the scroll is flat, and it can only be flat. Turning a three-dimensional into a flat surface is not a simple matter of flattening, and there are many things to consider.

Therefore, it is impossible to simply learn the corresponding magic according to the scroll, and knowing this magic does not mean that the corresponding scroll can be made, and the conversion on both sides requires a lot of calculations and redesign.

In fact, the best thing to do now is to put down the greasy spell for a while and switch to other spells.

Although the effect of other spells is worse and the pertinence is not so strong, it can be compensated for by the number, if you can throw out a dozen or twenty scrolls in one go and carry out a saturation attack, it is estimated that no matter how fast the speed of the meerkat, it will not be able to dodge. Although no single mage can activate multiple scrolls at the same time, the only way to do it is to be fast.

However, Kaichi was not willing to give up so simply, and he decided to parse this magic and make it into a scroll.

Jia knew early on that his greasy surgery was outstanding, but he never looked into it. The greasy spell was a spell that he could forcibly construct before he became a full-fledged mage, and the greasy spell he learned was ordinary, no different from what his teacher, Imu, and others had learned. There's nothing special about it, and there's nothing unusual about it being released before becoming a full-fledged mage. But when he became a full-fledged mage and fixed the model of the greasy technique, the effect of the greasy technique became different and extraordinary.

At that time, he thought that the magic power would be strengthened after the spell model was fixed, but later he realized that this might be the feedback of the source sea under the advice of his teacher, but it was not complete, and only strengthened an existing magic. He thought this was a good thing at the time, after all, the power of the spell had been strengthened, but he didn't delve into it after just paying attention to it, and he didn't need any additional operations to use it.

But I didn't expect something to go wrong now.

He is still a little out of the way, not sensitive enough, but also because he has not been learning magic for a long time, many things are still being learned, and there is still knowledge from the previous life to be re-learned, so he lacks attention to the abnormality of the greasy technique.

He began to sit cross-legged, meditate deeply, and enter the spiritual sea. Meditation actually doesn't need a fixed posture, except for special needs, of course, but most meditation methods don't require special postures, but Jiayi probably watched too much TV, and sat down cross-legged unconsciously every time he meditated, and now he is used to it.

In the middle of his spiritual sea is the magic vortex, and at the bottom of the vortex is the magic circle that he fixed when he was promoted to become a full-fledged mage. There were several spell models floating in the vortex, all of which were simple spells such as fireballs, wind blades, ice arrows, etc., arranged in parallel in the vortex, but they did not rotate with the vortex, just like phantoms.

He found the spell model of the greasy spell, when he sank into the spiritual sea before, he saw that this spell model was no different from the rest of the spell models, but when he looked at it today, it seemed to have a different charm, I don't know if it was because of the mental effect or because he hadn't found it before.

Jia started by analyzing the spell model from scratch, combing through the existing model in the order in which he built the spell model, just like looking at a picture to find a difference.

It's just that the first time he passed it, he didn't notice anything different at all, probably because he was too careless, didn't observe carefully enough, or the changes were too small, or even the changes were not reflected in the spell model.

Kaichi didn't rush to make a conclusion, the study of spells was never achieved overnight, and he still had a killer feature.

Jia Yi first visualized the magic model in the spiritual sea in his mind, because it was only visualized in his mind, not constructed by spiritual power, so it was just a look, and it had no effect, just like a three-dimensional image.

Then he visualized the original model of the Greasy Technique, and then he slowly approached the original model and the model he had visualized first, superimposing them on top of each other until they coincided completely. At this moment, the difference between the two models is immediately visible.

At the beginning, the two models were completely overlapped, but as the model progressed, the new model gradually became different from the old one, and the angles of the backbone lines that made up the model were different, more here and less there, sometimes upward, sometimes downward. Although the themes are the same, there are many tweaks in the details. And the position of the runes in the model is also different, from the middle to the sides, slightly moved, and a little more empty in the middle.

Jiayi looked at the blank space in the middle part, and didn't understand what the principle was at all, so it was impossible for these adjustments to flow out of the blank.

He stared at it for a long time, then moved the old model away, and then looked at the blank space in the middle of the new model, and it seemed that a rune had been reconstructed between the backbones of the model, no matter from which point of view, it seemed to be a new rune. But this rune does not really exist, and the backbones that make up the rune are not really in contact with each other, but overlap from the outside to the inside.

Jia Yi wrote down this rune, and subconsciously, Jia Yi felt that this rune was a little extraordinary, of course, it was also possible that this was not a rune, but just a pattern of overlapping lines.

Then, Jia started to build this rune in the spiritual sea, but just after the construction was successful, a huge spell fluctuation came out, stirring Jia Yi's spiritual sea fiercely, just like an earthquake, the rune was also torn apart and dissipated. Jia Yi felt as if his head had been put in a big bell, and then he knocked it hard, and his whole head was buzzing, and he was so weak that he couldn't sit still.

Fortunately, his spirit was strong enough, and this accident did not cause any substantial damage, and after resting for a while, he gradually calmed down.

Jia Yi opened his eyes and let out a long sigh of relief, he was really scared to death just now, it was too reckless.

Few people dare to directly construct runes that they don't understand in the spiritual sea, and they generally operate in the spiritual sea when the outside world fully understands the effect of the runes. If there is an accident in the spiritual sea, it is a traumatic injury to the spiritual sea, which is more troublesome than internal and external injuries, after all, it can be regarded as brain-dead.

It's just that Jia Yi felt that this rune was analyzed from the greasy technique, and felt that it shouldn't be too powerful, and there was also a sense of not having too many expectations, so he directly constructed it in the spiritual sea. But he didn't think that this rune was not really constructed in the model of the greasy technique, and just a shadow increased the power of the greasy technique.

Fortunately, there was no irreparable accident, otherwise Jiayi would have cried. After being afraid, Jia Yi was a little happy, after all, he had mastered a powerful rune, although he didn't know what it did. But this is an experience he would never want to come back again.
